Description of problem:
The simple attached code causes an internal compiler error in gcc version 3.1
20011127 (Red Hat Linux Rawhide 3.1-0.10)

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Save file
2.type g++ -c prep2.C
3.See the error
	

Actual Results:  When I compile the attached code, the compiler reports:

prep2.C:47: Internal error #20010605.
prep2.C:47: Internal compiler error in build_secondary_vtable, at cp/class.c:
   672
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.


Expected Results:  The source should have compiled. If I change almost anything
in the file, the code compiles fine. If I change

class I :
  public G,
  public H 
{
};

To:

class I :
  public H,
  public G 
{
};

That is, just change the order of the listed parent classes, the compile works fine.
